PROCESS IN MANUFACTURING WALL-FACING TILES QF THE FAIENCE KIND.

To all whom it may concern:

Be it known that 'I, GEoRcEs DELBROUGK, a subject of the King ofBelgium, and resident of Brussels, Belgium, have invented certain newand useful Improvements in Processes for Manufacturin Wall-Facing Tilesof 'the Faience Kind, 0 which the following is a specification.

This invention relates to a process for manufacturing wall facing tilesof the faience kind.

In the drawing :Figure 1 is a perspective view of an embodiment of myinventhen covered with a first coating 2 of good oil color, cold enamel,ripolin or any other product of a similar kind colored in the shadewhich it is desired to obtain. One afterward allows it to dry during 48hours and then the glass plate is coated with a second coating 3covering the first one and after this second coating has been allowed todry as it has been stated for the first one, a third coating is appliedon the two first named ones. On this well dried thirdcoating one spreadsby means of a sieve, pitch 4,

. asphaltum or any other similar product adapted to melt at a .lowtemperature. The whole 1s then covered, always by means of a sieve, withfine cinder waste 5. The glass plate covered as above described is thenexposed to a temperature gradually raised to between and degrees andallowed to cool when the itch is conveniently molten. The gradualincrease of the heat hasfor its efi'ect not to roduce a change of thecolor and neverthe ess this heat determines the fusion of the pitch. y

The. advantage of this invention is to allow the employment of oilcolors or cold enamel and simllar products in the mann 'facture of wallfacings of the faience kind. The't'hickness of the transparent glasssheet rotects and covers the color which is viewed rom the outsidethrough the glass sheet. The pitch molten in a'hot state on the colortherefore brings the color between itself and the lass sheet. y

The g ass has for its effect to protect the color from any contactpossible from the Specification of Letters Patent.

outside and the layer of pitch protects it from being "injured by the,moisture of the walls and furthermore allows of the perfect adherence ofthe product to the cement employed for securing the tiles in position.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent is I l. A process for manufacturing wall facingtiles of the kind described consisting in cleaning the back of y atransparent glass plate, applying thereto, a color coating, allowing todry, applying to the color coating an'agglomerating substance adapted tomelt at a low temperature, applying on the said agglomeratin'g substancea layer of fine cin- -der waste, causing the said agglomeratingsubstance to melt by gradually heating the whole and allowing the wholeto cool, substantially as and for the purpose set forth.
